I have, burned into my brain, images of a graphic helicopter crash complete with charred human remains. I can see it as clearly today as I did then. Mom came into the room and quickly changed the channel.
That whole mentality continued until the mid-70's. I thought my babysitters were nuts...jeans with peace signs sewn on them....total goofballs. My third grade teacher even had a "music break" during the day, where we listened to anti-war songs.
I have always resented growing up following so immediately behind them...because they completely destroy everything that they touch.
You can blame Dan Rather for a lot of that; but the other two nightly news channels did much of the same thing, starting in '68!
I'm so sorry that you had to live through that, as such a little child.
